Example

[0031]The present invention will be explained and illustrated below in association with several embodiments to be described later, in particular, the cross groove joint of eight ball type. However, it is noted that the present invention is not limited to the eight ball type joint, but is applicable to the cross groove joint of any ball type, for example, having six, eight, ten, or more balls.

[0032]Referring to FIGS. 5-10 of the drawings, the cross groove type constant velocity joints of the present invention are described herein in details with several exemplary or preferred embodiments thereof. However, the following descriptions of such embodiments are intended primarily for illustrating the principles and exemplary constructions of the constant velocity joints of the present invention, and the present invention is not specifically limited to these exemplary embodiments. Thus, one skilled in the art can appreciate or recognize that various modifications and substitutions can be ma...

Abstract

A constant velocity joint for a drive system comprises: an outer joint member having a plurality of inwardly facing outer ball grooves, the outer ball grooves consisting of a first group of grooves and a second group of grooves with composite or non-linear groove pattern; an inner joint member disposed inside the outer joint member and having a plurality of outwardly facing inner ball grooves consisting of a first group of grooves and a second group of grooves with composite or non-linear groove pattern, each inner ball groove of the inner joint member being coupled with a corresponding outer ball groove of the outer joint member generally in crossed pair; and a cage having circumferentially displaced cage windows to accommodate a plurality of balls therein. The groove patterns of the ball grooves can be a combination of skewed grooves and non-linear grooves, a combination of non-linear grooves such as a curved groove or a compositely shaped groove, or a combination of linear grooves and non-linear grooves.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a cross groove type constant velocity joint for use in a drive system, and more particularly, to a cross groove type constant velocity joint having composite groove shapes, typically for use in a drive system of, for example, an automobile for transmitting rotational torque between two rotating shafts thereof.BACKGROUND OF THE INVENTION[0002]A cross groove type constant velocity joint (hereinafter to be referred as a “cross groove joint”) is one type of constant velocity universal joints used for transmitting rotational torque between the rotating shafts (i.e., the driving shaft and the driven shaft), typically for the drive system of automobiles. The cross groove joint includes an outer joint member with a plurality of ball grooves formed on the inner surface thereof, and an inner joint member with a plurality of ball grooves formed on the outer surface thereof, in which the corresponding ball grooves of the outer joint m...
